Je Tsongkhapa has a commentary on Asanga's Ethics Chapter that Tatz has translated. If anyone competent in Tibetan has the inclination, would you please re-translate these verses from Je Rinpoche's conclusion:

[Concluding Verses]To achieve buddhahood one enters the Greater Vehicle:This must be a set rule for all efforts.The basics of this path are resolve and implementation:Take them on and affirm them accordingly.

To say, as some do, though not training as bodhisattvas,That they yet have a path to the omniscient state,(98b) Though not proposed by the buddhas, their sons, or the learned,That the vajra vehicle and that of the perfectionsDiffer in prohibitions and in their injunctionsIs the height of folly, merely a flight of fancy:The basics of the general Greater Vehicle,The good and stainless path, for these unlucky ones disappears.

If you set about to enter the vajra vehicle,First create the thought of awakening and take the vow,Which are the topics of the immaculate scripturesAs explained by Maitreya, Nagarjuna, and Asanga;Take on the practice of six perfections as the basis,And then the path of Vajrayana in addition.That is the best-vehicle path that is not deficient;Others only delight those who are foolish.

My mistake, I was thinking that the quoted passages were entirely from the Yogacarabhumi. I thought that tracking down the Sanskrit or Chinese could be possible. I am not sure if the Tibetan text has been translated into Chinese or not.
